Speaking of plugins, Joost de Valk has published some of his thought process behind charging for his latest plugin release. I found this bit interesting:

There are some (though few) donations, there are people ordering website reviews, hiring me as a consultant etc. But we’d make more money if we didn’t release those plugins. That’s the cold and harsh reality. I’m not willing to stop releasing those plugins though. I’ve always said they’ll be free and I want to keep those that I’ve released for free, free.

In the post he says the sales of his Video SEO plugin have gone well, and he’ll be selling another plugin soon.
